I have installed ubuntu 10.x in my virtual box. From that i am upgrading the ubuntu machine to 12.04. Will the older versions[10.x] still remain in my machine or only the latest version will be available. If older versions available then how to clear my older versions of ubuntu? Please don't tell that install a new version of ubuntu.
Reasons for this is cause an app I use supports only older kernel versions.And I need newer Ubuntu versions cause they're supported(still have repos)and support for gnome shell.I currently use Ubuntu 10.04.
I have to run application based on Geant4 simulation (from geant4.cern.ch). The application was created using older version of geant4 (version 9.2) which requires that my Linux have C++ compiler also in old version. And the suitable versions are gcc-4.1.2 and gcc-4.2.1. But at the moment I have Ubuntu 12.04 LTS and it has gcc 4.6 or something. How can I install older version of gcc ?
Hi, I am a very recent convert to Ubuntu/Kubuntu when my older Windows laptop crashed. I was able to get it working again by downloading an Ubuntu iso via thumbdrive and boot thru it. I admit my grandson provided me with some advise as to how. After working with Ubuntu 12.04 for awhile, I found it a little too basic looking and just today switched to Kubuntu.
